Wow, I have never used System.Reflection.DynamicMethod before. Thank the author.

This Kata is not about Cartesian product, it's about adding custom methods for LINQ queries with accept various types. This is the problem of this Kata, because description must talk about it. And absolutly useless Func<> delegate, which do nothing except concat your result...

Actual is not the input, actual is what your function returned, expected is the correct result.

Could somebody explain me how to get "actual" input in C#?

Duplicate.

Thanks for this Kata

Approved~~good Kata！

Finally, First 2kyu.

Same message popped up right now.

Thanks!! It is one of the best Kata I have done so far. I hope you will create more Katas like this one in the future!

Try now.

LoL...

"Description cannot be approved, recent changes from related record must be merged first."

I included them in the description as people asked for all essential information to be in the text. But I don't see a problem in that too. I'll approve and you alter it as you see fit.

Hopefully it works now.
Before you accept it, it seems that you have decided not to include the stats in the solution setup, do you want me to remove them from the translation?

When I try to approve your translation I get a message saying:
"Description cannot be approved, recent changes from related record must be merged first."
